:'''Steps to Manually set Audacity Input Interface:'''

:# In the Audacity menu-bar, select '''EDIT''' -> '''Preferences''' :# The '''Audacity Preferences''' dialog box application will appear.:# Remain in the default '''Devices''' tab.:# In the Interface Section, select '''Jack''' to be the host.:# Click '''OK''' to save changes.

:'''The procedure to select different instruments in Audacity is subtle! I don't know if this is the BEST method, but here is what I know works...'''

:Assuming that you are still in the Audacity Preferences dialog box ('''Devices''' tab), in the Recording section, click on the drop down menu for Devices. If you are running your Jack Audio server, and running Qsynth as well as Hydrogen, you should see 3 devices:

:* '''Hydrogen''' (Drum Machine):* '''Qsynth''' (Keyboards):* '''System''' (Vocals via Microphone)

:'''Let's now add in each of these elements, track-by-track...'''

:In the '''Audacity Preferences dialog box, under devices, select "Hydrogen"''' (Drum Machine), and close the dialog box.

:'''NOTE: Each time you want to "lay-down" a track using a different device, you MUST go to Audacity Preference dialog box and select your Recording Device...'''

:Hydrogen is a drum machine application. It is useful to allow the user to record drumming patterns (to be looped), or entire drumming patterns for a song.

:Although I prefer a REAL drummer, you can use a drum machine as a basis for your song. After the song has been recorded (via Audacity), you can mute the drumming pattern and replace with real drums...

:The Hydrogen drum machine is pretty easy to use. Just press RECORD, and then click on an appropriate drum sound. The drumming pattern loops, so you can take your time to build more complex drumming patterns. Various drumming patterns can be saved and then can be added in a sequence to build a song... This application also has a "pattern" mode and a "song" mode...

:Create a drumming pattern, and press play on the hydrogen application to test out the drumming pattern. Stop the drumming pattern.

:When you are ready to record, click the record button in the Audacity transport toolbar, and then click the play button in the hydrogen application. Don't worry if there is blank audio, since you can always cut the unwanted portions of the track after recording. When finished, then click the stop button in Hydrogen, and then click the stop button in Audacity. It is recommended to immediately click the rewind button to set the position to the beginning of the track.

:Plug the guitar, bass guitar into the USB port. In this case for the Tascam US-122 USB Device, switch one of the front ports from "mic" to "guitar". Make certain that the input volume control knob is somewhere in-between zero and full setting.

:In the '''Audacity Preferences dialog box, under devices, select "system"'''. The device "system" relates to the USB inputs for vocal and guitar, or any device that plugs into the USB device (eg. XLR microphone, or a 1/4 inch plug).

:When you are ready to record, click the record button in the Audacity transport toolbar, and then listen to the recorded tracks as a guide when to start playing your guitar or bass guitar. When finished, then click the stop button in Hydrogen, and then click the stop button in Audacity. It is recommended to immediately click the rewind button to set the position to the beginning of the track.
